I think most people track it down with foundation shades
I don't really like to use celebs because their tone fluctuates a lot because of multiple factors like season, lightening even hair color
the particular brand I use is sheglam from shein
shein.com/SHEGLAM-Skinfinite-Hydrating-Foundation-Chantilly-Flawless-Dewy-Foundation-Hydrating-Coverage-Invisible-Pore-Concealer-Poreless-Non-Greasy-Lightweight-Natural-Soft-Liquid-Foundation-p-12182241-cat-1868.html?mallCode=1
the reason I used this foundation is because it's very cheap so I can buy multiple shades and switch as I lighten
if I feel like I'm getting lighter I try one shade higher than my usual foundation if it fits perfectly I know I lighten a shade
I use this board to track it down
right now I'm shade Cappucino , my initial shade was around Russet and my new ultimate goal is Almond
